copious free time

copious free time /n./ [Apple; orig. fr. the intro to Tom
Lehrer's song "It Makes A Fellow Proud To Be A Soldier"]
1. [used ironically to indicate the speaker's lack of the quantity
in question] A mythical schedule slot for accomplishing tasks held
to be unlikely or impossible. Sometimes used to indicate that the
speaker is interested in accomplishing the task, but believes that
the opportunity will not arise. "I'll implement the automatic
layout stuff in my copious free time." 2. [Archly] Time reserved
for bogus or otherwise idiotic tasks, such as implementation of
chrome, or the stroking of suits. "I'll get back to him
on that feature in my copious free time."
